Intrestingly,
Even if CGI is told to print instantly, the apache knows that the "long
job" is doing something and might need to print out. This is why it
waits for the "long job" to be over before it releases the STDOUT pipe.
I thought I will fork it, close the PIPE on child which is supposed to
do the long job so that apache doesn't wait for it.
At this time child will continue to do the long job. Apache releases the
pipe held by the parent and IE dislays the new page.
Interestingly, it is not helping

Is there really a need to use forking? Instead, how about:
1. CGI prints instant reply.
2. CGI execs long job (you *are* using exec and not system, right?),
and
exits.
3. long job sends mail (exec or system or a subroutine) when it's done.
You'd need to pass $loginid to the long job of course.
